Can I set the value of flow and pump head to a specific number like the value from SCADA?

Hello Pan,

The pump heads and flows should be fixed as per the demand of your network. The general workflow is such that based on the network demands, the pumps are "sized" and then optimized. If you are having historical SCADA data for pumps a better approach would be to first design (head and flow) the pumps as per your demands and then compare it with the historical data to check if the provided head and flow are sufficient.

You can refer the Chapter titled "Importing SCADA Data" in the Quick Start Lessons of WaterGEMS which outlines the basic steps for importing historical SCADA data and comparing with your model.

Once you compare the SCADA data with your model you will understand how your pump is functioning as compared to historical readings.

Hope this helps.

Thank you for your advice, but I just have the flow and head value from SCADA not the whole file.

So it might be too complicated to import SCADA data for me.  

I just want to fix the pump flow and head and see what will these two source react in the model.
